Unions say schools need time to plan for a return to opening, after the Government made a u-turn on bringing Leaving Cert students back to school for three days a week.
They will instead be taught remotely until the end of this month.
The Government reversed its decision after pressure from the teaching unions the ASTI and TUI, who said their members wouldn't teach in class.
The government has also scrapped plans for special needs education to resume on Monday.
